After my latest update with sudo pacman -Syu, I’m unable to now open the Matlab application using command line or otherwise:
■■■■■■■■■■■■■ ~]$ matlab
MATLAB is selecting SOFTWARE OPENGL rendering.
■■■■■■■■■■■■■■■ ~]$
which is strange because previously the same message would pop up but Matlab would open immediately. Has it been removed after the update? I dont see it listed in my packages installed. Then shouldn’t it have thrown an error when requested on prompt itself?
You used pacman to update the base system.
matlab is a package from AUR
It may need to be rebuilt against the now changed base system.
Oh I see! the installation files before the update are still in /usr/local/MATLAB/R2024b/bin/matlab
Should I remove them and re-install in the new updated base system?
All the previous time I updated the system using pacman, I did not have to rebuild Matlab. I wonder what has changed now?
you should rebuild the matlab package
It may not work easily when you are on Manjaro stable branch.
Packages from the AUR should be rebuilt after a system sync/update; usually with pamac build <packagename>.
If you installed the following Matlab version from AUR, I note that it was last updated on 2023-09-19 – in this case, rebuilding it might serve no useful purpose.
Additional (for reference):
It looks like these instructions are most useful for installing Matlab on Arch based distributions;
